PLATE THIMBLE non PIPES.

Application filed July 23, 1926. 7 Serial 170,124,417.

The invention relates to improvements in plate assemblies apertured to receive pipes of heating systems or the like and intended to cover relatively large openings in floors, walls, etc., provision being made whereby the pipes may change their positions with respect to the plate assemblies under the influence of expansion and contraction.

It is the object of the invention to provide a new and improved construction which, while being exceptionally simple and inexpensive, will be eflicient and durable and will present a good appearance.

lVith the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Fig. 1 is a plan view of the improved plate assembly, illustrating the associated pipe in transverse section.

Fig. 2 is a transverse sectional view on line 2-2 ofFig. 1.

Fig. 3 is a longitudinal section on line 3 3 of Fig. 1.

Fig. 4 is a disassembled plan view.

In the drawing above briefly described, the numerals 5 and 6 designate a pair of sub stantially rectangular sheet metal plates, said plates having longitudinal edges 7 in contact with each other and being notched as at 8 to form a receiving slot for a pipe 9.

The outer longitudinal edges of the plates 5 and 6 are bent laterally to provide stifl'ening flanges 10, and the ends of said plates are similarly bent to provide additional flanges 11. Channeled sheet metalstrips 12 receive the flanges 11 of the two plates 5 and (3, said strips slidably engaging the flanges of one plate but being secured to the flanges of the other plate, for instance by spot welding or by center punching at the points 13.

Two smaller, sheet metal plates 14 and 15, contact with the inner sides of the plates 5 and 6 and have inner longitudinal edges 16 disposed in contact with each other and notched as at 17 to form an opening for the pipe 9, which opening is alined with the slot 88. A sheet metal strip 18 extends across one end portion of the plates 14 and 15, said strip being secured to one of these plates by spot welding 19 or other desired means, and being pivoted to the other plate as indicated at 20.

It will be observed that the lengths of all of the plates 5, 6, 14 and 15, extend in the same direction and that the slot 88 is elongated in this same direction, and any suitable means, such as the sheet metal ledges 21, may be carried by the plates 5 and 6 and slidably engaged with the outer longitudinal edge portions of the plates 14 and 15, so as to slidably connect the-two sets of plates, permitting shifting of the pipe 9 under changes in temperature, but insuring that the plates 14 and 15 shall cover the slot 8 8, regardless of the extent to which th pipe moves.

The plates 14 and 15 are held against separation by the means 21, and the two plates 5 and 6 which carry said means 21, may be secured to the wall, floor or the like, by any desired means such as screws 22, said plates being formed with openings 23 through which to pass these fasteners.

It will be seen from the foregoing that a device has been provided which is exceptionally simple and inexpensive, and may be easily manufactured and installed. On account of the advantages existing for the details herein presented, such details are preferably followed. However, within the scope of the invention as claimed, variations may be made.

hat is claimed is 1. A device of the class described, comprising two substantially rectangular plates disposed in a common plane and having longitudinal edges in contact with each other, said} plates being notched to form a pipe-receiving slot and having laterally bent flanges on their ends and on their outer longitudinal edges but not on their abutting edges, a pair of channeled strips receiving 9 the end flanges of said plates, said strips being secured to the end flanges of one plate and being slidably engaged with those of the other plate, a pair of smaller plates at one side of the first named plates notched to form a pipe-receiving opening, and means for holding said smaller plates slidably engaged with the first named plates PATENT OFFICE.

2. A device of the class described, comprising two substantially rectangular plates disposed in a common plane and having longitudinal edges in contact with each other, said plates being notched to form a pipereceiving slot and having laterally bent flanges on their ends and on their outer longitudinal edges but not on their abutting edges, a pair of channeled strips receiving the end flanges of said plates, said strips being secured to the end flanges of one plate and being slidably engaged With those of the other plate, a pair of smaller plates at one side of the first named plates having longi tudinal edges in contact with each other and notched to form a pipe-receiving opening, a metal strip extending across contiguous end portions of said smaller plates, said strip being secured to one plateand pivoted to the other, and ledges carried by the first named plates and slidably engaged with the outer longitudinal edges of the smaller plates.

3. In a device of the class, described,two relatively small substantially rectangular plates having longitudinal edges disposed in contact and notched to receive a. pipe, a strip extending across one end portion of. said plates, said strip being secured to one plate and pivoted to the other, a pair of larger plates at one side of the smaller plates notched to form a pipe-receiving slot, means for holding the larger plates in assembled relation, and means slidably connecting the tWo sets of plates and holding the smaller plates against separation.

t. In a device of the class described, two substantially rectangular plates disposed in a common plane and having longitudinal edges in contact With each other, said plates being. notched to form a pipe-receiving hole and having laterally bent flanges on their ends and ontheir outer longitudinal edges but not on their abutting edges, and a pair of channeled strips receiving the end flanges of said plates, said strips being secured to the end flanges of one plate and being slidab'ly engaged With those of the other plate.

In testimony whereof I have hereunto afiixed my signature.

JOHN W. FARLEY.
